DSM is becoming an important and integral intervention strategy in power system operations in developed as well as developing countries and newer technologies are being introduced with the objectives of energy optimization, peak power reduction, improved reliability, reduction in emissions, etc. In countries such as India it assumes added importance in the context of rapid demand growth and our vision to provide 24X7 reliable power supply to all at affordable rates, focus on increased share of renewable energy, promotion of e-mobility, etc.
Duly recognizing these challenges, various StateElectricity Regulatory Commissions (SERC) have notified regulations on DSM defining the process chain, action areas, roles of different players, etc. The DSM strategies could vary from utility to utility depending on the consumer mix, end use energy consumption pattern of different consumers, socio-economic factors, physical characteristics of the utility, operational features, etc. Development of utility-specific DSM strategies assumes importance in this context.
In Karnataka, the State Electricity Regulatory Commission (KERC) has notified DSM Regulations in 2015. As per the regulation, distribution licensees are required to identify DSM targets in their respective license area and submit the plan for approval of the commission. In accordance with these regulations, in 2017, The Energy and Resources Institute (TERI) with funding support from the MacArthur Foundation, had undertaken a study for the Mangalore Electricity Supply CompanyLtd. (MESCOM) in Karnataka. The study covered a comprehensive load research; identification of potential areas for DSM intervention in different sectors like domestic, commercial, industrial and agriculture; suitable business models for implementation; and a suggested action plan.
The video explains the concept of Demand Side Management and TERI’s study recommendations for MESCOM.

Decarbonising our electricity supply is essential to meet the UK’s climate change targets, particularly so in light of the ongoing drive to electrify transport and heat. In this context renewables like solar and wind are likely to feature prominently because of their tumbling costs in recent decades. Designing power systems with high shares of renewables requires models that capture their spatiotemporal variability and how they interaction with the rest of the system, e.g. the transmission network, electricity storage, etc. This in turn means developing a class of hybrid energy models that have high spatial and temporal resolution and simultaneously make planning and operational decisions. Here we introduce the high spatial and temporal resolution electricity system model highRES which we have developed and outline two applications of the model in a UK context: i) how the variability of weather from one year to the next impacts power systems with high shares of renewables, ii) taking an energy-land-water, or nexus, perspective to designing low carbon power systems for Great Britain in 2050.

http://brs.li/BRSCarbon Have you ever wondered which carbon performs the best, or whether a media reactor really out-performs a media bag? We're going to cover it all in this episode of BRStv.
Carbon is integral in maintaining a healthy tank, as it removes a large range of contaminants and organic compounds from our aquariums. Most result from the continual adding of foods, fish waste and algae break down over time. Carbon is also capable of removing many medications, water treatments and accidental contaminants that may have been introduced to the tank by accident.
One of the biggest reasons reefers use carbon is to remove the yellowing pigments in the water which impact perceived coral coloration and light penetration.
At a glance, you may not think your water is yellow but there's a pretty good chance it is. A quick way to find out is to drain some water from the tank into a white bucket that's about the same depth as your tank. You'll quickly see how yellow the water is, especially when compared to a bucket of freshly mixed saltwater.
The good news is that the proper use of carbon can return your tanks water to the pristine blue you're looking for.
So what type of carbon should you use? There are three basic types commonly offered to the aquarium industry; bituminous, lignite and specialty carbon. They may look similar to the plain eye, but at a microscopic level they all have rather different pore structures, and work differently in the aquarium.
Each of the pore networks has unique properties ideal for different contaminants. You'll want to select a carbon known for having a pore structure similar in size to the molecules you're trying to remove.
Any of them are likely to work to some extent, but what you probably want to know is which one is the BEST available, or simply which is the best value when considering performance and price available.
Bituminous, while not the best performing due to its smaller pore structure, is the most commonly used carbon in our industry. This is likely due to it being a hard carbon which produces less dust, making it easier to rinse. Bituminous carbon is what you will find most readily available on the retail market.
Lignite carbon has a larger pore structure which makes it more efficient at removing larger dissolved organic compounds and yellowing pigments. It does cost a few dollars more, but it's still quite affordable. At BRS, we sell about 3x as much lignite as bituminous due to its higher performance.
The third type of carbon that we sell is ROX 0.8. There is a price premium on this carbon, however it makes up about 70% of our total carbon sales due to its unique advantages.
ROX is a proprietary blend of different carbon sources which have been powdered and extruded into tiny pellets, which are super hard making it almost dust-free and rinses in seconds.
ROX is designed for ultra-pure water applications like pharmaceutical intermediaries where the contaminant removal standards are not only extreme but it is also critical the carbon itself adds as little to the water as possible.
We performed a few standard tests using 200g of carbon in a BRS reactor and heater RO/DI water to help identify their performance. The tests included:
- The Iodine number which measures performance and ability to absorb small molecules.
- The Methylene blue which tests for the ability to remove medium sized molecules.
- The molasses efficiency test which tests for the ability to remove larger molecules.
ROX 0.8 carbon removed a wide range of pore sizes which resulted in nearly the complete removal of both the molasses as well as the methlyene blue.
Our BRS bituminous carbon is a bit different than most on the market in that its grade splits the different between typical bituminous and lignite. It removed most of the contaminants, but left behind a green tint which means it did not remove all of the yellow and blue tints.
The standard bituminous commonly available in the industry performed pretty poorly.
Implementing carbon in your aquarium is super easy! The ideal solution would be a media reactor where you can ensure the entire volume of water passes through the carbon several times a day.
Another method would be to throw some carbon in a media bag, rinse under cold tap water (or better yet, RO/DI water) and place it in a high-flow area of the sump. I don't typically use lignite in media bags due to the dust, but you can if you want.
Which method is better? We tested this, too. The media reactor was able to remove most of the contaminants in the water in about 75 minutes, while a media bag with 400g of carbon took about 8 hours.
While it did take about 7x longer than the reactor, the bags, there's no denying that a well-placed filter bag of carbon is more effective than many think. It's definitely a legit option for those who don't have room in the budget for a reactor.

Joe Lassiter is a deep thinker and straight talker focused on developing clean, secure and carbon-neutral supplies of reliable, low-cost energy. His analysis of the world's energy realities puts a powerful lens on the stubbornly touchy issue of nuclear power, including new designs for plants that can compete economically with fossil fuels. We have the potential to make nuclear safer and cheaper than it's been in the past, Lassiter says. Now we have to make the choice to pursue it.

By way of several real world case studies, Chris shows why carbon accounting is the key to reducing fossil fuel dependency and increasing long-term, stable profits.

This is a very unusual heating wire that uses a core of very fine carbon fibre strands encased in a soft rubber sleeve. It has a resistance of about 33 ohms per metre (about 10 ohms a foot) so suitable lengths can be directly powered from the mains supply. Shorter lengths like 1m (40") can be run directly from 12V and will dissipate about 4-5W of heat per metre along the length of the cable.
This material seems to be designed for underfloor heating purposes. Probably laid in a pattern and then screeded over to protect it.
I was trying to work out how to connect it and the only indication I've come across is that you strip it to expose the carbon fibres and then fold them back on the insulation before ramming it into the end of a copper tube. In one image it showed it being crimped too.

Power supply

A power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.

Every power supply must obtain the energy it supplies to its load, as well as any energy it consumes while performing that task, from an energy source. Depending on its design, a power supply may obtain energy from various types of energy sources, including electrical energy transmission systems, energy storage devices such as a batteries and fuel cells, electromechanical systems such as generators and alternators, solar power converters, or another power supply.

All power supplies have a power input, which receives energy from the energy source, and a power output that delivers energy to the load. In most power supplies the power input and output consist of electrical connectors or hardwired circuit connections, though some power supplies employ wireless energy transfer in lieu of galvanic connections for the power input or output. Some power supplies have other types of inputs and outputs as well, for functions such as external monitoring and control.

Power Supply (EP)

Power Supply is an EP that was released by New York based chiptune group Anamanaguchi in 2006. The EP was released via the record label and website 8bitpeoples. The track "Helix Nebula" was featured as the theme song of the former GamesRadar podcast TalkRadar.

Recording studio

A recording studio is a facility for sound recording and mixing. Ideally both the recording and monitoring spaces are specially designed by an acoustician to achieve optimum acoustic properties (acoustic isolation or diffusion or absorption of reflected sound that could otherwise interfere with the sound heard by the listener).

Recording studios may be used to record musicians, voice-over artists for advertisements or dialogue replacement in film, television or animation, foley, or to record their accompanying musical soundtracks. The typical recording studio consists of a room called the "studio" or "live room", where instrumentalists and vocalists perform; and the "control room", where sound engineers sometimes with producer(s) as well operate either professional audio mixing consoles or computers (post 1980s) with specialized software suites to manipulate and route the sound for analogue or digital recording. Often, there will be smaller rooms called "isolation booths" present to accommodate loud instruments such as drums or electric guitar, to keep these sounds from being audible to the microphones that are capturing the sounds from other instruments, or to provide "drier" rooms for recording vocals or quieter acoustic instruments.

Components are often designed to generate as little heat as possible, and computers and operating systems may be designed to reduce power consumption and consequent heating according to workload, but more heat may still be produced than can be removed without attention to cooling. Use of heatsinks cooled by airflow reduces the temperature rise produced by a given amount of heat. Attention to patterns of airflow can prevent the development of hotspots. Computer fans are widely used along with heatsinks to reduce temperature by actively exhausting hot air. There are also more exotic cooling techniques, such as liquid cooling.

All modern day processors are designed to cut out or reduce their voltage (which translates to power usage) and/or clock speed if the internal temperature of the processor exceeds a specified limit.

Fractal Design

Fractal Design was a US software company, originally known as Fractal Software and founded in 1985. It merged into MetaCreations in 1997. It was initially known as Fractal Technology, and produced several best-selling creative software packages for the PC and Macintosh platforms. Its initial success was Fractal Painter, a natural media drawing program released in 1990. It acquired Ray Dream Software in 1996. In 1997, it was merged into MetaCreations. The products in its portfolio were later sold off to other major software producers including Corel and Microsoft.

Historian

Allen's career began with history and he specialized in Christian socialism within Canada. In 1971, he published a work entitled The Social Passion, chronicling the history of the Canadian social gospel from the 1890s to 1929. In the book he proposed that the social gospel supplied the reform movement with a type of ideology. He said it ultimately failed because the concept translated poorly between English and Canadian society and that the structure of the churches did not lend itself to promoting social change. The book was criticized because it focused too strongly on central Canada and ignored trends in the Maritimes and Western Canada.

Richard Allen (bishop)

Richard Allen (February 14, 1760 – March 26, 1831) was a minister, educator, writer, and one of America's most active and influential black leaders. In 1794 he founded the African Methodist Episcopal Church (AME), the first independent black denomination in the United States. He opened his first AME church in 1794 in Philadelphia, Pennsylvania.

Elected the first bishop of the AME Church in 1816, Allen focused on organizing a denomination where free blacks could worship without racial oppression and where slaves could find a measure of dignity. He worked to upgrade the social status of the black community, organizing Sabbath schools to teach literacy and promoting national organizations to develop political strategies.

Early life and freedom

Richard Allen was born into slavery on February 14, 1760, on the Delaware property of Benjamin Chew. When he was a child Allen and his family were sold to Stokeley Sturgis, who had a plantation in Delaware. When Sturgis had financial problems he sold Richard's mother and three of his five siblings. Allen had an older brother and sister left with him and the three began to attend meetings of the local Methodist Society, which was welcoming to slaves and free blacks. They were encouraged by their master Sturgis, although he was unconverted. Richard taught himself to read and write. He joined the Methodists at age 17. He began evangelizing and attracted criticism from local slave owners. Allen and his brother redoubled their efforts for Sturgis so no one could say his slaves did not do well because of religion.

This is a very unusual heating wire that uses a core of very fine carbon fibre strands encased in a soft rubber sleeve. It has a resistance of about 33 ohms per metre (about 10 ohms a foot) so suitable lengths can be directly powered from the mains supply. Shorter lengths like 1m (40") can be run directly from 12V and will dissipate about 4-5W of heat per metre along the length of the cable.
This material seems to be designed for underfloor heating purposes. Probably laid in a pattern and then screeded over to protect it.

Decarbonising our electricity supply is essential to meet the UK’s climate change targets, particularly so in light of the ongoing drive to electrify transport and heat. In this context renewables like solar and wind are likely to feature prominently because of their tumbling costs in recent decades. Designing power systems with high shares of renewables requires models that capture their spatiotemporal variability and how they interaction with the rest of the system, e.g. the transmission network, electricity storage, etc. This in turn means developing a class of hybrid energy models that have high spatial and temporal resolution and simultaneously make planning and operational decisions. Here we introduce the high spatial and temporal resolution electricity system model highRES which we ...

How to get pristine blue water in your aquarium with carbon

http://brs.li/BRSCarbon Have you ever wondered which carbon performs the best, or whether a media reactor really out-performs a media bag? We're going to cover it all in this episode of BRStv.
Carbon is integral in maintaining a healthy tank, as it removes a large range of contaminants and organic compounds from our aquariums. Most result from the continual adding of foods, fish waste and algae break down over time. Carbon is also capable of removing many medications, water treatments and accidental contaminants that may have been introduced to the tank by accident.
One of the biggest reasons reefers use carbon is to remove the yellowing pigments in the water which impact perceived coral coloration and light penetration.
At a glance, you may not think your water is yellow but there's...

Testing carbon fibre heating wire. (with flame test)

This is a very unusual heating wire that uses a core of very fine carbon fibre strands encased in a soft rubber sleeve. It has a resistance of about 33 ohms per metre (about 10 ohms a foot) so suitable lengths can be directly powered from the mains supply. Shorter lengths like 1m (40") can be run directly from 12V and will dissipate about 4-5W of heat per metre along the length of the cable.
This material seems to be designed for underfloor heating purposes. Probably laid in a pattern and then screeded over to protect it.
I was trying to work out how to connect it and the only indication I've come across is that you strip it to expose the carbon fibres and then fold them back on the insulation before ramming it into the end of a copper tube. In one image it showed it being crimped too....

DSM is becoming an important and integral intervention strategy in power system operations in developed as well as developing countries and newer technologies are being introduced with the objectives of energy optimization, peak power reduction, improved reliability, reduction in emissions, etc. In countries such as India it assumes added importance in the context of rapid demand growth and our vision to provide 24X7 reliable power supply to all at affordable rates, focus on increased share of renewable energy, promotion of e-mobility, etc.
Duly recognizing these challenges, various StateElectricity Regulatory Commissions (SERC) have notified regulations on DSM defining the process chain, action areas, roles of different players, etc. The DSM strategies could vary from utility to utility depending on the consumer mix, end use energy consumption pattern of different consumers, socio-economic factors, physical characteristics of the utility, operational features, etc. Development of utility-specific DSM strategies assumes importance in this context.
In Karnataka, the State Electricity Regulatory Commission (KERC) has notified DSM Regulations in 2015. As per the regulation, distribution licensees are required to identify DSM targets in their respective license area and submit the plan for approval of the commission. In accordance with these regulations, in 2017, The Energy and Resources Institute (TERI) with funding support from the MacArthur Foundation, had undertaken a study for the Mangalore Electricity Supply CompanyLtd. (MESCOM) in Karnataka. The study covered a comprehensive load research; identification of potential areas for DSM intervention in different sectors like domestic, commercial, industrial and agriculture; suitable business models for implementation; and a suggested action plan.
The video explains the concept of Demand Side Management and TERI’s study recommendations for MESCOM.

Decarbonising our electricity supply is essential to meet the UK’s climate change targets, particularly so in light of the ongoing drive to electrify transport and heat. In this context renewables like solar and wind are likely to feature prominently because of their tumbling costs in recent decades. Designing power systems with high shares of renewables requires models that capture their spatiotemporal variability and how they interaction with the rest of the system, e.g. the transmission network, electricity storage, etc. This in turn means developing a class of hybrid energy models that have high spatial and temporal resolution and simultaneously make planning and operational decisions. Here we introduce the high spatial and temporal resolution electricity system model highRES which we have developed and outline two applications of the model in a UK context: i) how the variability of weather from one year to the next impacts power systems with high shares of renewables, ii) taking an energy-land-water, or nexus, perspective to designing low carbon power systems for Great Britain in 2050.

http://brs.li/BRSCarbon Have you ever wondered which carbon performs the best, or whether a media reactor really out-performs a media bag? We're going to cover it all in this episode of BRStv.
Carbon is integral in maintaining a healthy tank, as it removes a large range of contaminants and organic compounds from our aquariums. Most result from the continual adding of foods, fish waste and algae break down over time. Carbon is also capable of removing many medications, water treatments and accidental contaminants that may have been introduced to the tank by accident.
One of the biggest reasons reefers use carbon is to remove the yellowing pigments in the water which impact perceived coral coloration and light penetration.
At a glance, you may not think your water is yellow but there's a pretty good chance it is. A quick way to find out is to drain some water from the tank into a white bucket that's about the same depth as your tank. You'll quickly see how yellow the water is, especially when compared to a bucket of freshly mixed saltwater.
The good news is that the proper use of carbon can return your tanks water to the pristine blue you're looking for.
So what type of carbon should you use? There are three basic types commonly offered to the aquarium industry; bituminous, lignite and specialty carbon. They may look similar to the plain eye, but at a microscopic level they all have rather different pore structures, and work differently in the aquarium.
Each of the pore networks has unique properties ideal for different contaminants. You'll want to select a carbon known for having a pore structure similar in size to the molecules you're trying to remove.
Any of them are likely to work to some extent, but what you probably want to know is which one is the BEST available, or simply which is the best value when considering performance and price available.
Bituminous, while not the best performing due to its smaller pore structure, is the most commonly used carbon in our industry. This is likely due to it being a hard carbon which produces less dust, making it easier to rinse. Bituminous carbon is what you will find most readily available on the retail market.
Lignite carbon has a larger pore structure which makes it more efficient at removing larger dissolved organic compounds and yellowing pigments. It does cost a few dollars more, but it's still quite affordable. At BRS, we sell about 3x as much lignite as bituminous due to its higher performance.
The third type of carbon that we sell is ROX 0.8. There is a price premium on this carbon, however it makes up about 70% of our total carbon sales due to its unique advantages.
ROX is a proprietary blend of different carbon sources which have been powdered and extruded into tiny pellets, which are super hard making it almost dust-free and rinses in seconds.
ROX is designed for ultra-pure water applications like pharmaceutical intermediaries where the contaminant removal standards are not only extreme but it is also critical the carbon itself adds as little to the water as possible.
We performed a few standard tests using 200g of carbon in a BRS reactor and heater RO/DI water to help identify their performance. The tests included:
- The Iodine number which measures performance and ability to absorb small molecules.
- The Methylene blue which tests for the ability to remove medium sized molecules.
- The molasses efficiency test which tests for the ability to remove larger molecules.
ROX 0.8 carbon removed a wide range of pore sizes which resulted in nearly the complete removal of both the molasses as well as the methlyene blue.
Our BRS bituminous carbon is a bit different than most on the market in that its grade splits the different between typical bituminous and lignite. It removed most of the contaminants, but left behind a green tint which means it did not remove all of the yellow and blue tints.
The standard bituminous commonly available in the industry performed pretty poorly.
Implementing carbon in your aquarium is super easy! The ideal solution would be a media reactor where you can ensure the entire volume of water passes through the carbon several times a day.
Another method would be to throw some carbon in a media bag, rinse under cold tap water (or better yet, RO/DI water) and place it in a high-flow area of the sump. I don't typically use lignite in media bags due to the dust, but you can if you want.
Which method is better? We tested this, too. The media reactor was able to remove most of the contaminants in the water in about 75 minutes, while a media bag with 400g of carbon took about 8 hours.
While it did take about 7x longer than the reactor, the bags, there's no denying that a well-placed filter bag of carbon is more effective than many think. It's definitely a legit option for those who don't have room in the budget for a reactor.

I was trying to work out how to connect it and the only indication I've come across is that you strip it to expose the carbon fibres and then fold them back on the insulation before ramming it into the end of a copper tube. In one image it showed it being crimped too.

Decarbonising our electricity supply is essential to meet the UK’s climate change targets, particularly so in light of the ongoing drive to electrify transport and heat. In this context renewables like solar and wind are likely to feature prominently because of their tumbling costs in recent decades. Designing power systems with high shares of renewables requires models that capture their spatiotemporal variability and how they interaction with the rest of the system, e.g. the transmission network, electricity storage, etc. This in turn means developing a class of hybrid energy models that have high spatial and temporal resolution and simultaneously make planning and operational decisions. Here we introduce the high spatial and temporal resolution electricity system model highRES which we have developed and outline two applications of the model in a UK context: i) how the variability of weather from one year to the next impacts power systems with high shares of renewables, ii) taking an energy-land-water, or nexus, perspective to designing low carbon power systems for Great Britain in 2050.

How to get pristine blue water in your aquarium with carbon

http://brs.li/BRSCarbon Have you ever wondered which carbon performs the best, or whether a media reactor really out-performs a media bag? We're going to cover it all in this episode of BRStv.
Carbon is integral in maintaining a healthy tank, as it removes a large range of contaminants and organic compounds from our aquariums. Most result from the continual adding of foods, fish waste and algae break down over time. Carbon is also capable of removing many medications, water treatments and accidental contaminants that may have been introduced to the tank by accident.
One of the biggest reasons reefers use carbon is to remove the yellowing pigments in the water which impact perceived coral coloration and light penetration.
At a glance, you may not think your water is yellow but there's a pretty good chance it is. A quick way to find out is to drain some water from the tank into a white bucket that's about the same depth as your tank. You'll quickly see how yellow the water is, especially when compared to a bucket of freshly mixed saltwater.
The good news is that the proper use of carbon can return your tanks water to the pristine blue you're looking for.
So what type of carbon should you use? There are three basic types commonly offered to the aquarium industry; bituminous, lignite and specialty carbon. They may look similar to the plain eye, but at a microscopic level they all have rather different pore structures, and work differently in the aquarium.
Each of the pore networks has unique properties ideal for different contaminants. You'll want to select a carbon known for having a pore structure similar in size to the molecules you're trying to remove.
Any of them are likely to work to some extent, but what you probably want to know is which one is the BEST available, or simply which is the best value when considering performance and price available.
Bituminous, while not the best performing due to its smaller pore structure, is the most commonly used carbon in our industry. This is likely due to it being a hard carbon which produces less dust, making it easier to rinse. Bituminous carbon is what you will find most readily available on the retail market.
Lignite carbon has a larger pore structure which makes it more efficient at removing larger dissolved organic compounds and yellowing pigments. It does cost a few dollars more, but it's still quite affordable. At BRS, we sell about 3x as much lignite as bituminous due to its higher performance.
The third type of carbon that we sell is ROX 0.8. There is a price premium on this carbon, however it makes up about 70% of our total carbon sales due to its unique advantages.
ROX is a proprietary blend of different carbon sources which have been powdered and extruded into tiny pellets, which are super hard making it almost dust-free and rinses in seconds.
ROX is designed for ultra-pure water applications like pharmaceutical intermediaries where the contaminant removal standards are not only extreme but it is also critical the carbon itself adds as little to the water as possible.
We performed a few standard tests using 200g of carbon in a BRS reactor and heater RO/DI water to help identify their performance. The tests included:
- The Iodine number which measures performance and ability to absorb small molecules.
- The Methylene blue which tests for the ability to remove medium sized molecules.
- The molasses efficiency test which tests for the ability to remove larger molecules.
ROX 0.8 carbon removed a wide range of pore sizes which resulted in nearly the complete removal of both the molasses as well as the methlyene blue.
Our BRS bituminous carbon is a bit different than most on the market in that its grade splits the different between typical bituminous and lignite. It removed most of the contaminants, but left behind a green tint which means it did not remove all of the yellow and blue tints.
The standard bituminous commonly available in the industry performed pretty poorly.
Implementing carbon in your aquarium is super easy! The ideal solution would be a media reactor where you can ensure the entire volume of water passes through the carbon several times a day.
Another method would be to throw some carbon in a media bag, rinse under cold tap water (or better yet, RO/DI water) and place it in a high-flow area of the sump. I don't typically use lignite in media bags due to the dust, but you can if you want.
Which method is better? We tested this, too. The media reactor was able to remove most of the contaminants in the water in about 75 minutes, while a media bag with 400g of carbon took about 8 hours.
While it did take about 7x longer than the reactor, the bags, there's no denying that a well-placed filter bag of carbon is more effective than many think. It's definitely a legit option for those who don't have room in the budget for a reactor.

We need nuclear power to solve climate change | Joe Lassiter

Joe Lassiter is a deep thinker and straight talker focused on developing clean, secure and carbon-neutral supplies of reliable, low-cost energy. His analysis of the world's energy realities puts a powerful lens on the stubbornly touchy issue of nuclear power, including new designs for plants that can compete economically with fossil fuels. We have the potential to make nuclear safer and cheaper than it's been in the past, Lassiter says. Now we have to make the choice to pursue it.

By way of several real world case studies, Chris shows why carbon accounting is the key to reducing fossil fuel dependency and increasing long-term, stable profits.

Testing carbon fibre heating wire. (with flame test)

This is a very unusual heating wire that uses a core of very fine carbon fibre strands encased in a soft rubber sleeve. It has a resistance of about 33 ohms per metre (about 10 ohms a foot) so suitable lengths can be directly powered from the mains supply. Shorter lengths like 1m (40") can be run directly from 12V and will dissipate about 4-5W of heat per metre along the length of the cable.
This material seems to be designed for underfloor heating purposes. Probably laid in a pattern and then screeded over to protect it.
I was trying to work out how to connect it and the only indication I've come across is that you strip it to expose the carbon fibres and then fold them back on the insulation before ramming it into the end of a copper tube. In one image it showed it being crimped too.

Power supply

A power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.

Every power supply must obtain the energy it supplies to its load, as well as any energy it consumes while performing that task, from an energy source. Depending on its design, a power supply may obtain energy from various types of energy sources, including electrical energy transmission systems, energy storage devices such as a batteries and fuel cells, electromechanical systems such as generators and alternators, solar power converters, or another power supply.

All power supplies have a power input, which receives energy from the energy source, and a power output that delivers energy to the load. In most power supplies the power input and output consist of electrical connectors or hardwired circuit connections, though some power supplies employ wireless energy transfer in lieu of galvanic connections for the power input or output. Some power supplies have other types of inputs and outputs as well, for functions such as external monitoring and control.
